Merge branch 'core/rcu' into perf/core
Steve Rostedt asked for the merge of a single commit, into both
the RCU and the perf/tracing tree:
| Josh made a change to the tracing code that affects both the
| work Paul McKenney and I are currently doing. At the last
| Kernel Summit back in August, Linus said when such a case
| exists, it is best to make a separate branch based off of his
| tree and place the change there. This way, the repositories
| that need to share the change can both pull them in and the
| SHA1 will match for both. Whichever branch is pulled in first
| by Linus will also pull in the necessary change for the other
| branch as well.
